FreeBSD: Make freebsd a variant, fix unittests and tools/build-on-freebsd.
- Simplify the logic of 'variant' in util.system_info
much of the data from https://github.com/hpcugent/easybuild/wiki/OS_flavor_name_version
- fix get_resource_disk_on_freebsd when running on a system without
an Azure resource disk.
- fix tools/build-on-freebsd to replace oauth with oauthlib and add
bash which is a dependency for tests.
- update a fiew places that were checking for freebsd but not using
the util.is_FreeBSD()
FreeBSD: replace ifdown/ifup with "ifconfig down" and "ifconfig up".
Fix the issue caused by different commands on Linux and FreeBSD. On Linux,
we used ifdown and ifup to enable and disable a NIC, but on FreeBSD, the
counterpart is "ifconfig down" and "ifconfig up".
FreeBSD: fix cdrom mounting failure if /mnt/cdrom/secure did not exist.
The current method is to attempt to mount the cdrom (/dev/cd0), if it is
successful, /dev/cd0 is configured, otherwise, it is not configured. The
problem is it forgets to check whether the mounting destination folder is
created or not. As a result, mounting attempt failed even if cdrom is
ready.
main: Don't use templater to format the welcome message
Some versions of Cheetah returned everything as unicode by default (not
utf-8 or ascii) and some varieties of syslog would choke on unicode.
Jinja2 is probably fine, but Python's format() is perfectly adequate for
a short message like the welcome message.

docs: Automatically generate module docs form schema if present.
We have started adding jsonschema definitions for cloudconfig modules
(cc_ntp). This branch allows us render sphinx docs using the module's
shema definition instead of using the module's docstring.
This allows us to avoid duplicating schema documentation in the
module-level docstring and schema definition. The corresponding module
documentation is extended a bit to differentiate between config schema and
potential examples.
